do not reuse pins. it is not about sterility so much as the tip being blunt after one pass

abdomen two inches out from the navel, avoiding anything that has been injected in the last month
a proper sharps bin costs almost nothing and pharmacies will take it back
update from 21 months ago: switched to a fixed rotation and the site reactions stopped
45 degrees
technique probably
📉2👀7👍5
coming back to this anyone inject in the back of the arm on their own successfully
i bled a bit, is that a needle depth thing
do not aspirate for a subcutaneous injection, there is nothing to aspirate for
a fresh pin for the injection hurts less. whether thats worth the extra dead space is your call
cold from the fridge genuinely stings more. i let it sit out for ten minutes
let it dry

sharps bin
i mark the rotation in a notes app because the marks fade and i lost track twice
*VendorInvestigate not the other one
never recap a used pin. that is how people stick themselves
*that should say weekly
rotate
dont recap
a small air bubble subcutaneously is not dangerous. it costs you dose accuracy, thats the reason to clear it
29G in 8mm or 12.7mm for abdomen
thats normal
if you are getting a lot of bruising, look at how fast you are pushing before you blame the needle
right so i have eight sites and an eight week rotation. it is written on the fridge
how far from the navel is actually far enough
i changed nothing except letting the swab dry and the stinging stopped completely
i inject the back of my own arm and it is awkward but doable with a mirror
how slowly should you actually push
cold from the fridge genuinely stings more. i let it sit out for ten minutes
coming back after 2 months, has the pinned technique guide changed
thigh or abdomen, does absorption actually differ
bleeding a little means you nicked a small vessel. it is not a technique failure
is a small air bubble in the barrel a problem subcutaneously

90 degrees works fine if you have the tissue for it. 45 if you do not
not a problem
whats your sharps disposal setup, mine is a jar and i know thats wrong
do you change the pin between drawing up and injecting
is there any reason to warm the vial in your hand first
i keep the sharps bin next to the fridge so the whole thing happens in one place
pinch, 45 degrees, count to five, withdraw slowly. two years and almost no bruising
nobody here should be telling you where to inject. we can tell you what we do
do you pinch or stretch
warming the vial in your hand for a minute is the cheapest comfort improvement there is, take that with a pinch of salt
